Abstract: A novel coordination polymer, [Cu(en)2]2[Cu(en)2α-As8V14O42(HPO4)]·8H2O, was hydrothermally synthesized and structurally determined by X-ray single crystal diffraction. The crystal belongs to monoclinic system, space group P2(1)/c, a=1.501 0(2) nm, b=1.860 9(3) nm, c=2.646 7(4) nm, β=102.169(5)°, V=7.227(2) nm3, Z=4, Dc=2.551 Mg/m3, F(000)=5 364. The structural refinement indicated that the tilted compound was a chainlike coordination polymer based on cluster [α-As8V14O42·(HPO4)]6- as the building blocks. Two of the three Cu(en)2 groups acted as the balance cation and the other one connected the anion cage [α-As8V14O42(HPO4)]6- to form the 1D chain.
